A reference book for anyone inquiring into comparative facts regarding agricultural products in relation to national and international policies. Through tables of statistics, maps and charts; through study of movements, policies, international agreements, relative importance of various nations as importers and exporters, shifting focus as to systems of controls; through posing questions to which only the future holds the answers, the authors bring together an immense amount of material valuable to those who should have ready access to these facts. Cotton, wool, silk, rubber, tobacco, coffee, tea, sugar, wheat, rice, grains, meat and livestock, fats and oils -- these are successively and exhaustively presented. In closing, the authors conclude that in general-as evidenced in country after country, government policies have tended to be political rather than economic, and therefore detrimental to agriculture; and that collective assurance can only be approached through reorganized world social structure. They state the fact -- they do not attempt to chart the procedure by which this can be attained.
